Create a flavorful prawn-infused oil using prawn shells, canola oil, and tarragon. This oil enhances the prawn flavor in dishes or can even be used to make mayo.
1: Combine the shells and oil in a pot on medium-high heat.
2: Bring the oil up to 325°F for 5 minutes, then add tarragon and remove from heat to cool.
3: Strain the mixture into an airtight container and store it in the fridge for up to a week.
